In a silver Nissan left behind, investigators found the bullet-riddled body of David Braaf. He worked as a night manager at the nearby RaceTrac gas station, and was well known to the owner of the pizza shop and many others in the area.

"David is a good kid," friend Adam Dronceler said. "He has a wife and two kids. He knows about my daughter. He asks about my daughter every day."

RaceTrac officials declined to comment, but added that they're cooperating with police. And while they have turned over surveillance video, they said it has nothing to do with the homicide. No one was at Braaf's home when WPBF 25 News' Terri Parker knocked on the door there Tuesday.

Police said the Nissan had been stolen during a carjacking in Riviera Beach several days ago.

Those in the area told Parker they're getting nervous; many of them declined to be interviewed on camera, and one said he was planning to start carrying his gun.
